1. FIELD

Disclosed herein are prodrugs of propofol, methods of making prodrugs of propofol, pharmaceutical compositions of prodrugs of propofol and methods of using prodrugs of propofol and pharmaceutical compositions thereof to treat or prevent diseases or disorders such as migraine headache pain and post-chemotherapy or post-operative surgery nausea and vomiting.

2. BACKGROUND

Propofol (2,6-diisopropylphenol), (1), is a low molecular weight phenol that is widely used as an intravenous sedative-hypnotic agent in the induction and maintenance of anesthesia and/or sedation in mammals. The advantages of propofol as an anesthetic include rapid onset of anesthesia, rapid clearance, and minimal side effects (Langley et al., Drugs 1988, 35, 334–372). Propofol may mediate hypnotic effects through interaction with the GABA_(A) receptor complex, a heterooligomeric ligand-gated chloride ion channel (Peduto et al., Anesthesiology 1991, 75, 1000–1009.).

Propofol is rapidly metabolized in mammals with the drug being eliminated predominantly as glucuronidated and sulfated conjugates of propofol and 4-hydroxypropofol (Langley et al., Drugs 1988, 35, 334–372). Propofol clearance exceeds liver blood flow, which indicates that extrahepatic tissues contribute to the overall metabolism of the drug. Human intestinal mucosa glucuronidates propofol in vitro and oral dosing studies in rats indicate that approximately 90% of the administered drug undergoes first pass metabolism, with extraction by the intestinal mucosa accounting for the bulk of this presystemic elimination (Raoof et al., Pharm. Res. 1996, 13, 891–895). Accordingly, oral administration of propofol is of little therapeutic utility because of extensive first-pass metabolism.

Propofol has a broad range of biological and medical applications, which are evident at sub-anesthetic doses and include treatment and/or prevention of intractable migraine headache pain (Krusz et al., Headache 2000, 40, 224–230; Krusz, International Publication No. WO 00/54588). Propofol, when used to maintain anesthesia, causes a lower incidence of post-operative nausea and vomiting (“PONV”) in comparison to common inhalational anesthetic agents; numerous controlled clinical studies support the anti-emetic activity of propofol (Tramer et al., Br. J. Anaesth. 1997, 78, 247–255; Brooker et al., Anaesth. Intensive Care 1998, 26, 625–629; Gan et al., Anesthesiology 1997, 87, 779–784). Propofol also has anti-emetic activity when used in conjunction with chemotherapeutic compounds (Phelps et al., Ann. Pharmacother. 1996, 30, 290–292; Borgeat et al., Oncology 1993, 50, 456–459; Borgeat et al., Can. J. Anaesth. 1994, 41, 1117–1119; Tomioka et al., Anesth. Analg. 1999, 89, 798–799). Nausea, retching and/or vomiting induced by a variety of chemotherapeutic agents (e.g., cisplatin, cyclophosphamide, 5-fluorouracil, methotrexate, anthracycline drugs, etc.) has been controlled by low-dose propofol infusion in patients refractory to prophylaxis with conventional anti-emetic drugs (e.g., serotonin antagonists and corticosteroids).

Propofol may also be used to treat patients with refractory status epilepticus (Brown et al., Pharmacother. 1998, 32, 1053–1059; Kuisma et al., Epilepsia 1995, 36, 1241–1243; Walder et al., Neurology 2002, 58, 1327–1332; Sutherland et al., Anaesth. Intensive Care 1994, 22, 733–737). Further, the anticonvulsant effects of propofol have also been demonstrated in rat efficacy models at sub-anesthetic doses (Holtkamp et al., Ann. Neurol. 2001, 49, 260–263; Hasan et al., Pharmacol. Toxicol. 1994, 74, 50–53).

Propofol may also be used as an antioxidant (Murphy et al., Br. J. Anaesth. 1992, 68, 613–618; Sagara et al., J. Neurochem. 1999, 73, 2524–2530; Young et al., Eur. J. Anaesthesiol. 1997, 14, 320–326; Wang et al. Eur. J. Pharmacol. 2002, 452, 303–308). Propofol, at doses typically used for surgical anesthesia, has observable antioxidant effects in humans (De la Cruz et al., Anesth. Analg. 1999, 89, 1050–1055). Pathogenesis or subsequent damage pathways in various neurodegenerative diseases involve reactive oxygen species and accordingly may be treated or prevented with antioxidants (Simonian et al., Pharmacol. Toxicol. 1996, 36, 83–106). Examples of specific neurodegenerative diseases which may be treated or prevented with anti-oxidants include, but are not limited to, Friedrich's disease, Parkinson's disease, Alzheimer's disease, Huntington's disease, amyotrophic lateral sclerosis (“ALS”), multiple sclerosis (“MS”), Pick disease, inflammatory diseases and diseases caused by inflammatory mediators such as tumor necrosis factor (TNF) and IL-1.

A significant problem with the therapeutic use of propofol is its lack of appreciable solubility in water. Accordingly, propofol must be specially formulated in aqueous media using solubilizers or emulsifiers (Briggs et al., Anaesthesia 1982, 37, 1099–1101). For example, in a current commercial product (Diprivan®, Astra-Zeneca) an oil-in-water emulsion (the emulsifier is the lecithin mixture Intralipid®), is used to formulate propofol (Picard et al., Anesth. Analg. 2000, 90, 963–969).

One potential solution to the insolubility of propofol in aqueous solution, which avoids the use of additives, solubilizers or emulsifiers, is a water-soluble, stable propofol prodrug that is converted to propofol in vivo. (Hendler et al., International Publication No. WO 99/58555; Morimoto et al., International Publication No. WO 00/48572; Hendler et al., U.S. Pat. No. 6,254,853; Stella et al., U.S. Patent Application No. US2001/0025035; Hendler, U.S. Pat. No. 6,362,234; International Publication No. WO 02/13810; Sagara et al., J. Neurochem. 1999, 73, 2524–2530; Banaszczyk et al., Anesth. Analg. 2002, 95, 1285–1292; Trapani et al., Int. J. Pharm. 1998, 175, 195–204; Trapani et al., J. Med. Chem. 1998, 41, 1846–1854; Anderson et al., J. Med. Chem. 2001, 44, 3582–3591; Pop et al., Med. Chem. Res. 1992, 2, 16–21). A significant problem with existing propofol prodrugs is their stability under physiological conditions, which prevents release of therapeutically significant concentrations of propofol, particularly when the prodrug is orally administered. Thus, there is a need for propofol prodrugs, which are sufficiently labile under physiological conditions to provide therapeutically significant concentrations of propofol, particularly, when the prodrug is orally administered.

In still other embodiments of a compound of Formula (I), n is 1, Y is O, R¹⁸ is hydrogen or methyl, A is CR⁴, B is CR⁵, D is CR⁶, E is CR⁷, G is CR⁸, R⁶ is —W[C(O)]_(k)Z(CR⁹R¹⁰)_(r)CO₂R¹¹, each of R⁵, R⁵, R⁷ and R⁸ is independently hydrogen, C₁₋₄ alkyl, C₁₋₄ alkoxy, C₁₋₄ alkoxycarbonyl, carboxyl, halo or hydroxyl, W is NR¹⁴, k is 1, Z is CR¹⁵R¹⁶, r is 2, and each of R⁹, R¹⁰, R¹¹, R¹⁴, R¹⁵ and R¹⁶ is independently hydrogen or C₁₋₄ alkyl.

Compounds of structural Formula (I) may be substrates for intestinal anion transporters such as the sodium-dependent multivitamin transporter (“SMVT”) and members of the proton-dependent monocarboxylate transporter (“MCT”) family. The SMVT transporter typically mediates the intestinal absorption of the water-soluble vitamins pantothenate and biotin whereas natural substrates for intestinally expressed monocarboxylate transporters include lactate and pyruvate (Wang et al., J. Biol. Chem. 1999, 274, 14875–14883; Halestrap et al., Biochem. J. 1999, 343, 281–299). The intestinal permeability of certain monocarboxylate drugs (e.g., carindacillin, atorvastatin, etc.) may be mediated via interaction with MCTs. Monocarboxylate transporter 1 (“MCT1”) expression extends from the upper regions of the mammalian gastrointestinal tract through the large intestine, where it plays a role in absorption of short-chain fatty acids (e.g., butyrate) produced by colonic bacteria. Molecules transported by such colonically expressed proteins are candidates for formulation in sustained oral delivery systems, where controlled release of the drug during its prolonged residence in the colon leads to sustained systemic drug levels relative to conventional immediate release formulations. Similarly, compounds that passively diffuse across the colonic mucosa may be administered via oral sustained release formulations.

Methods for determining whether compounds may serve as substrates for the SMVT transporter are disclosed in Example 3 herein (see Section 5).

4.3 Synthesis

Compounds disclosed herein may be obtained via the synthetic methods illustrated in Schemes 1–7. Compounds of Formula (I) where n is 0, Y is a bond or CR¹R², W is a bond, k is 1, Z is O or NR¹⁷ and R¹¹ is hydrogen, i.e., compound (7), are prepared according to methods illustrated in Scheme 1. The aromatic or heteroaromatic carboxylic acid compound (2) is first converted into a reactive acylating agent (3), by treatment with a phosgene equivalent, thionyl halide or related activating agent. Reaction with propofol in the presence of base, and optionally a catalyst such as DMAP, affords bis-ester (4). Removal of the carboxylate protecting group, conversion to a reactive acylating agent by treatment with an appropriate coupling reagent, followed by addition of protected amino acid or hydroxyl acid (5) generates compound (6). Finally, removal of the carboxylate protecting group affords the desired compound (7).

Alternatively, ortho-disubstituted aromatic or heteroaromatic derivatives related to compound (7), i.e., compound (10), can be expediently prepared starting with anhydride compound (8), as illustrated in Scheme 2.

The aromatic or heteroaromatic carboxylic acid compound (11) is first converted into a reactive acylating agent (12), by treatment with a phosgene equivalent, thionyl halide or related activating agent. Reaction with propofol in the presence of base, and optionally a catalyst such as DMAP, affords ester (13). Removal of the protecting group from either the oxygen or nitrogen atom in (13), followed by treatment with acylating agent (14) or (15) affords, after deprotection of the carboxylate moiety, compound (16).

Compounds of Formula (I) where n is 0, Y is O or NR³, W is a bond, k is 1, Z is O or NR¹⁷ and R¹¹ is hydrogen, i.e., compound (20), are prepared according to methods illustrated in Scheme 4. The phenolic or anilino compound (17) is reacted with a phosgene equivalent to give respectively the chloroformate or amidoyl chloride species (18). Displacement of the chloro group by treatment with propofol in the presence of base, and optionally a catalyst like DMAP, affords carbonate or carbamate (19). Alternatively, compound (19) can be elaborated directly from compound (17) by reaction with the propofol chloroformate derivative (31). Coupling of the carboxyalkyl moiety (5) proceeds as previously described to afford compound (20).

Compounds of Formula (I) where n is 1, Y is a bond or CR¹R², W is a bond, k is 1, Z is O or NR¹⁷ and R¹¹ is hydrogen, i.e., compound (27), are prepared according to methods illustrated in Scheme 6. The acyloxyalkyl ether (26) is prepared from aromatic or heteroaromatic carboxylic acid compound (2), either by sequential halide displacements of compound (32) in the presence of a base or metal promoter agent (typically a soluble Ag⁺ or Hg²⁺ salt), or by reaction with the haloalkyl (or thioalkyl) propofol ether (33). If X₂ in (25) is —SR (e.g., thiomethyl), activation by treatment with sulfuryl chloride or similar halogenating agents precedes displacement by propofol to generate compound (26). Coupling of the carboxyalkyl moiety (5) proceeds as previously described to afford compound (27).

Compounds of Formula (I) where n is 1, Y is a bond or CR¹R², W is O or NR¹⁴, k is 1, Z is CR¹⁵R¹⁶, O or NR¹⁷ and R¹¹ is hydrogen, i.e., compound (30), are prepared according to methods illustrated in Scheme 7. The acyloxyalkyl ether (29) is prepared from (11), either by sequential halide displacements of compound (32) under conditions previously described (i.e., in the presence of base or with a metal salt promoter), or by reaction with the haloalkyl (or thioalkyl) propofol ether (33). Removal of the protecting group from either the oxygen or nitrogen atom in (29), followed by treatment with acylating agent (14) or (15) affords, after deprotection of the carboxylate moiety, compound (30).

The present compounds and/or pharmaceutical compositions thereof, are preferably administered orally. Compounds and/or pharmaceutical compositions thereof may also be administered by any other convenient route, for example, by infusion or bolus injection, by absorption through epithelial or mucocutaneous linings (e.g., oral mucosa, rectal and intestinal mucosa, etc.). Administration can be systemic or local. Various delivery systems are known, (e.g., encapsulation in liposomes, microparticles, microcapsules, capsules, etc.) that can be used to administer compounds and/or pharmaceutical composition thereof.

In specific embodiments, it may be desirable to administer one or more compounds and/or pharmaceutical composition thereof locally to the area in need of treatment. This may be achieved, for example, and not by way of limitation, by local infusion during surgery, topical application, e.g., in conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers.

In certain embodiments, it may be desirable to introduce one or more compounds and/or pharmaceutical compositions thereof into the central nervous system by any suitable route, including intraventricular, intrathecal and epidural injection. Intraventricular injection may be facilitated by an intraventricular catheter, for example, attached to a reservoir, such as an Ommaya reservoir.

In some embodiments, compounds and/or pharmaceutical compositions thereof can be delivered via sustained release systems, preferably, oral sustained release systems. In some embodiments, a pump may be used (see Langer, supra; Sefton, 1987, CRC Crit Ref Biomed Eng. 14:201; Saudek et al., 1989, N. Engl. J. Med. 321:574).

In other embodiments, polymeric materials can be used (see “Medical Applications of Controlled Release,” Langer and Wise (eds.), CRC Pres., Boca Raton, Fla. (1974); “Controlled Drug Bioavailability,” Drug Product Design and Performance, Smolen and Ball (eds.), Wiley, New York (1984); Langer et al., 1983, J Macromol. Sci. Rev. Macromol Chem. 23:61; see also Levy et al., 1985, Science 228: 190; During et al., 1989, Ann. Neurol. 25:351; Howard et al., 1989, J. Neurosurg. 71:105). In still other embodiments, polymeric materials are used for oral sustained release delivery. Such polymers include, for example, sodium carboxymethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose and hydroxyethylcellulose. Other cellulose ethers have been described (Alderman, Int. J. Pharm. Tech. & Prod. Mfr. 1984, 5(3) 1–9). Factors affecting drug release are well known to the skilled artisan and have been described in the art (Bamba et al., Int. J. Pharm. 1979, 2, 307).

In other embodiments, enteric-coated preparations are used for oral sustained release administration. Coating materials include, for example, polymers with pH-dependent solubility (i.e., pH-controlled release), polymers with slow or pH-dependent rate of swelling, dissolution or erosion (i.e., time-controlled release), polymers that are degraded by enzymes (i.e., enzyme-controlled release) and polymers that form firm layers that are destroyed by an increase in pressure (i.e., pressure-controlled release).

In still other embodiments, osmotic delivery systems are used for oral sustained release administration (Verma et al., Drug Dev. Ind. Pharm. 2000, 26:695–708). In some embodiments, OROS™ osmotic devices are used for oral sustained release delivery devices (Theeuwes et al., U.S. Pat. No. 3,845,770; Theeuwes et al., U.S. Pat. No. 3,916,899).

For administration by inhalation, compounds may be conveniently delivered to the lung by a number of different devices. For example, a Metered Dose Inhaler (“MDI”) which utilizes canisters that contain a suitable low boiling propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas may be used to deliver compounds disclosed herein directly to the lung.

Alternatively, a Dry Powder Inhaler (“DPI)” device may be used to administer compounds to the lung (See, e.g., Raleigh et al., Proc. Amer. Assoc. Cancer Research Annual Meeting, 1999, 40, 397). DPI devices typically use a mechanism such as a burst of gas to create a cloud of dry powder inside a container, which may then be inhaled by the patient. A popular variation is the multiple dose DPI (“MDDPI”) system, which allows for the delivery of more than one therapeutic dose. For example, capsules and cartridges of gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of a compound and a suitable powder base such as lactose or starch for these systems.

Another type of device that may be used to deliver compounds to the lung is a liquid spray device supplied, for example, by Aradigm Corporation, Hayward, Calif. Liquid spray systems use extremely small nozzle holes to aerosolize liquid drug formulations that may then be directly inhaled into the lung.

In some embodiments, a nebulizer device is used to deliver a compound disclosed herein to the lung. Nebulizers create aerosols from liquid drug formulations by using, for example, ultrasonic energy to form fine particles that may be readily inhaled (see e.g., Verschoyle et al., British J. Cancer, 1999, 80, Suppl. 2, 96). Examples of nebulizers include devices supplied by Batelle Pulmonary Therapeutics (Columbus, Ohio) (See, Armer et al., U.S. Pat. No. 5,954,047; van der Linden et al., U.S. Pat. No. 5,950,619; van der Linden et al., U.S. Pat. No. 5,970,974).

In still other embodiments, an electrohydrodynamic (“EHD”) aerosol device is used to deliver a compound to the lung. EHD aerosol devices use electrical energy to aerosolize liquid drug solutions or suspensions (see e.g., Noakes et al., U.S. Pat. No. 4,765,539; Coffee, U.S. Pat. No. 4,962,885; Coffee, International Publication No. WO 94/12285; Coffee, International Publication No., WO 94/14543; Coffee, International Publication No., WO 95/26234, Coffee, International Publication No., WO 95/26235, Coffee, International Publication No., WO 95/32807). Electrochemical properties of a compound may be important parameters to optimize when delivering this compound to the lung with an EHD aerosol device; such optimization is routinely performed by one of skill in the art. EHD aerosol devices may more efficiently deliver compounds to the lung than existing pulmonary delivery technologies. Other methods of intra-pulmonary delivery of compounds are known to the skilled artisan and are within the scope of the present disclosure.

The compounds and/or pharmaceutical compositions thereof preferably, provide therapeutic or prophylactic levels of propofol upon in vivo administration to a patient. While not wishing to bound by theory, the promoiety or promoieties of the compounds may be cleaved either chemically and/or enzymatically. One or more enzymes present in the stomach, intestinal lumen, intestinal tissue, blood, liver, brain or any other suitable tissue of a mammal may enzymatically cleave the promoiety or promoieties of the compounds disclosed herein. The mechanism of cleavage is not important.

While not wishing to bound by theory, the promoiety or promoieties of the compounds disclosed herein may be cleaved prior to absorption by the gastrointestinal tract (e.g., within the stomach or intestinal lumen) and/or after absorption by the gastrointestinal tract (e.g., in intestinal tissue, blood, liver or other suitable tissue of a mammal). Propofol may remain conjugated to a promoiety during transit across the intestinal mucosal barrier to provide protection from presystemic metabolism. In some embodiments, compounds are essentially not metabolized to propofol within enterocytes, but are metabolized to the parent drug within the systemic circulation. Cleavage of the promoiety or promoieties of the compounds after absorption by the gastrointestinal tract, may allow these prodrugs to be absorbed into the systemic circulation either by active transport, passive diffusion or by a mixture of both active and passive processes. In some embodiments, compounds are actively absorbed through interaction with anion transporters like SMVT or MCT's.

Cleavage of the promoiety or promoieties of compounds after absorption by the gastrointestinal tract, may allow these prodrugs to be absorbed into the systemic circulation from the large intestine. In some embodiments, the compounds and/or pharmaceutical compositions thereof are administered as sustained release systems. In other embodiments, the compounds and/or pharmaceutical compositions thereof are delivered by oral sustained release administration. Preferably, in this embodiment, the compounds and/or pharmaceutical compositions are administered twice per day (more preferably, once per day).

5.5 Pharmaceutical Compositions

The present pharmaceutical compositions contain a therapeutically effective amount of one or more compounds, preferably in purified form, together with a suitable amount of a pharmaceutically acceptable vehicle, to provide the form for proper administration to a patient. When administered to a patient, the compounds and pharmaceutically acceptable vehicles are preferably sterile. Water is a preferred vehicle when a compound is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid vehicles, particularly for injectable solutions. Suitable pharmaceutical vehicles also include excipients such as starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propylene, glycol, water, ethanol and the like. The present pharmaceutical compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents. In addition, auxiliary, stabilizing, thickening, lubricating and coloring agents may be used.

Pharmaceutical compositions comprising a compound disclosed herein may be manufactured by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes. Pharmaceutical compositions may be formulated in conventional manner using one or more physiologically acceptable carriers, diluents, excipients or auxiliaries, which facilitate processing of compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen.

The present compositions can take the form of solutions, suspensions, emulsion, tablets, pills, pellets, capsules, capsules containing liquids, powders, sustained-release formulations, suppositories, emulsions, aerosols, sprays, suspensions, or any other form suitable for use. In some embodiments, the pharmaceutically acceptable vehicle is a capsule (see e.g., Grosswald et al., U.S. Pat. No. 5,698,155). Other examples of suitable pharmaceutical vehicles have been described in the art (see Remington's Pharmaceutical Sciences, Philadelphia College of Pharmacy and Science, 19th Edition, 1995). In other embodiment, pharmaceutical compositions are formulated for oral delivery.

Pharmaceutical compositions for oral delivery may be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, syrups, or elixirs, for example. Orally administered pharmaceutical compositions may contain one or more optional agents, for example, sweetening agents such as fructose, aspartame or saccharin, flavoring agents such as peppermint, oil of wintergreen, or cherry coloring agents and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the pharmaceutical compositions may be coated to delay disintegration and absorption in the gastrointestinal tract, thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active driving compound are also suitable for orally administered compounds and pharmaceutical compositions. In these later platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture. These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time delay material such as glycerol monostearate or glycerol stearate may also be used. Oral compositions can include standard vehicles such as mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate, etc. Such vehicles are preferably of pharmaceutical grade.

For oral liquid preparations such as, for example, suspensions, elixirs and solutions, suitable carriers, excipients or diluents include water, saline, alkyleneglycols (e.g., propylene glycol), polyalkylene glycols (e.g., polyethylene glycol) oils, alcohols, slightly acidic buffers between pH 4 and pH 6 (e.g., acetate, citrate, ascorbate at between about 5 mM to about 50 mM), etc. Additionally, flavoring agents, preservatives, coloring agents, bile salts, acylcarnitines and the like may be added.

Compounds may also be formulated in rectal or vaginal pharmaceutical compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides.

In addition to the formulations described previously, compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example, subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, compounds may be formulated with suitable polymeric or hydrophobic materials (for example, as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

When a compound is acidic, it may be included in any of the above-described formulations as the free acid, a pharmaceutically acceptable salt, a solvate or hydrate. Pharmaceutically acceptable salts substantially retain the activity of the free acid, may be prepared by reaction with bases and tend to be more soluble in aqueous and other protic solvents than the corresponding free acid form.

Liquid drug formulations suitable for use with nebulizers and liquid spray devices and EHD aerosol devices will typically include a compound with a pharmaceutically acceptable carrier. The pharmaceutically acceptable carrier may be a liquid such as alcohol, water, polyethylene glycol or perfluorocarbon. Optionally, another material may be added to alter the aerosol properties of the solution or suspension of compounds disclosed herein. Preferably, this material is liquid such as an alcohol, glycol, polyglycol or fatty acid. Other methods of formulating liquid drug solutions or suspension suitable for use in aerosol devices are known to those of skill in the art (see, e.g., Biesalski, U.S. Pat. No. 5,112,598; Biesalski, U.S. Pat. No. 5,556,611).

5.6 Combination Therapy

In certain embodiments, the compounds disclosed herein can be used in combination therapy with at least one other therapeutic agent. The compound and the therapeutic agent can act additively or, more preferably, synergistically. In some embodiments, a pharmaceutical composition comprising a compound disclosed herein is administered concurrently with the administration of another therapeutic agent, which can be part of the same pharmaceutical composition a or a different pharmaceutical composition. In other embodiments, a pharmaceutical composition comprising a compound disclosed herein is administered prior or subsequent to administration of another therapeutic agent.

Example 3 Analysis of Electrogenic Transport in SMVT-Expressing Xenopus Oocytes

Transporter Cloning: The complete open reading frame of human SMVT (SLC5A6) was amplified from human cDNA prepared from intestinal mRNA. Gene-specific oligonucleotide primers were designed against Genbank sequences (NM-021095). Amplified PCR products were cloned into a modified version of the mammalian expression vector pcDNA3 (termed pMO) that was engineered to contain the 5′ and 3′ untranslated regions from the Xenopus beta-globin gene. All clones were completely sequenced and tested for function by transient transfection in HEK293 cells. Radiolabeled ³H biotin was used to assess SMVT function (see method below).

Xenopus Oocyte Expression and Electrophysiology: cRNA for oocyte expression was prepared by linearization of plasmid cDNA and in vitro transcription using T7 polymerase (Epicentre Ampliscribe kit). Xenopus oocytes were prepared and maintained as previously described (Collins et al., Proc. Natl. Acad. Sci. 1997, 13:5456–5460) and injected with 10–30 ng RNA. Transport currents were measured 2–6 days later using two-electrode voltage-clamp (Axon Instruments). All experiments were performed using a modified oocyte ringers solution (90 mM NaCl, 2 mM KCl, 1.8 mM CaCl₂, 1 mM MgCl₂, and 10 mM NaHEPES, pH 7.4; in Na⁺-free solutions 90 mM choline chloride was substituted for NaCl). The membrane potential of oocytes was held at −60 mV and current traces acquired using PowerLab software (ADInstruments). Full 7-concentration dose-responses were performed for each compound. Current responses at the highest concentration were normalized to the maximal biotin elicited currents (i.e., at 0.5 mM). Half-maximal concentrations were calculated using non-linear regression curve fitting software (Prism) with the Hill co-efficient fixed to 1. To ensure that currents were specific for the over-expressed transporter, all compounds were tested against uninjected oocytes. Since SMVT requires Na⁺ for transport, transport specificity was confirmed by application of the compounds in a Na⁺-free solution.

Compound (101) elicited SMVT-specific currents significantly above background (at least 10% of I_(max) for biotin) when tested at 0.5 mM on oocytes expressing SMVT, confirming that this compound serves as a substrate for the transporter.
